(EN) METHOD FOR SYNTHESIZING A COMPOSITE MATERIAL CONSISTING OF A MIXTURE OF AFX- AND BEA-STRUCTURE ZEOLITES IN THE PRESENCE OF AN ORGANIC NITROGEN-CONTAINING STRUCTURING AGENT
(FR) PROCÉDÉ DE SYNTHÈSE D'UN MATÉRIAU COMPOSITE COMPOSÉ D'UN MÉLANGE DE ZÉOLITHES DE TYPE STRUCTURAL AFX ET DE TYPE STRUCTURAL BEA EN PRÉSENCE D'UN STRUCTURANT ORGANIQUE AZOTÉ
Abstract
(EN) The present invention relates to a method for preparing a zeolite composite material consisting of a mixture of AFX and BEA zeolites, said method comprising the following steps: i) in an aqueous medium, mixing specific ratios of an FAU zeolite having a molar ratio SiO2/Al2O3 of between 30 and 100 and a parameter P ze such that 3250 < Pze < 7200, with at least one FAU-structure zeolite having a molar ratio SiO2/Al2O3 of between 2 and 30 (upper limit excluded), at least one organic nitrogen-containing compound R, R being dihydroxide of 1,5-bis (methylpiperidinium) pentane, dihydroxide of 1,6-bis (methylpiperidinium) hexane and/or dihydroxide of 1,7-bis (methylpiperidinium) heptane, at least one source of at least one alkali and/or alkaline-earth metal M of valence n, so as to obtain a gel; and ii) subjecting said gel to hydrothermal treatment at a temperature of between 120°C and 220° C for a period of between 12 hours and 15 days.
(FR) La présente invention concerne un procédé de préparation d'un matériau composite zéolithique composé d'un mélange de zéolithes AFX et BEA, comprenant les étapes suivantes : i) le mélange en milieu aqueux, dans des proportions particulières, d'une zéolithe FAU ayant un rapport molaire Si02/Al203 compris entre 30 et 100 et un paramètre Pze tel que : 3250 < Pze < 7200, avec au moins une zéolithe de type structural FAU ayant un ratio molaire Si02/Al203 compris entre 2 et 30 (borne supérieure exclue), d'au moins un composé organique azoté R, R étant le dihydroxyde de 1,5-bis(méthylpiperidinium) pentane, dihydroxyde de 1,6-bis(méthylpiperidinium) hexane et/ou dihydroxyde de 1,7-bis(méthylpiperidinium) heptane, d'au moins une source d'au moins un métal alcalin et/ou alcalino-terreux M de valence n, pour obtenir un gel, ii) le traitement hydrothermal dudit gel obtenu à une température comprise entre 120°C et 220°C, pendant une durée comprise entre 12 heures et 15 jours.
